Anyone care to speculate if the 900W's advantage ONLY comes when the decibels peaks beyond the 600W's capability? Or should the 900W also offer a bit better control, and thus better resolution and fidelity?

Also, anyone know what the crossover point is between the small driver and the sub? (For the life of me, I'm not sure how such a small driver can handle mids and produce decibels approaching 100db.)

Finally, I see that it has analog input. If anyone has a DAC, one should be able to simply connect each of the Phantom to the DAC's analog output and run the pair in stereo - right now. Am I missing something?
